Ask the Editors: Honda 300EX Wiring Harness Compatibility
Dear ATVC: I have a 2000 Honda 300EX and am wondering if a main wiring harness from a 1997 will work on it? tank10rnk
Good news, the central wiring harness from a 1997 model 300EX will mate up to the 2000 without issue. In fact it is the same part # (32100-HM3-860) unchanged from years 1993-2000.
Looking at the above diagram, the harness in question would be # 7.
